John Engledow was a financial reformer and writer. He was Private Secretary to a political party active in the 1930s called the Constitutional Reform Party. Engledow wrote a number of pamphlets for the Party outlining its political manifesto which included combating Bolshevism, further development of the British Empire and the promotion of a reformed monetary system within Britain. The Party was also against what it saw as a perceived threat and the increasing influence from international finance and bankers which were encompassed into what the Party referred to as the "Hidden Hand". The Protocols Of The Elders Of Zion was clearly perceived as a legitimate document by Engledow and the Party judging by the content of existing pamphlet material.
This was scanned by the notorious Alexander Baron (born 1956) from an original copy held by the British Library, and transmitted by E-Mail to the great-grandson of the author who was doing some research into his family history and contacted me after seeing his great-grandfather's name on my website.
My apologies for the quality of the scan or lack thereof. The publication was scanned originally in JPG format - which includes a British Library watermark. The individual files were converted to PDF by the aforementioned gent, and collated by me.
